Pesticide Dilution Table

Fred FishelDepartment of Agronomy

This table is intended to offer the approximate amount of a pesticidal concentrate to be mixed with water to produce sprays for use on the farm and around the home. The desired percentage of active ingredient in the finished spray is obtained by mixing the indicated amount of formulation in 100 gallons of water. The number in parentheses ( ) indicates the amount to use in one gallon of water.

Some helpful equivalents

1 tablespoon (Tbs) = 3 teaspoons (tsp)

1 cup = 16 Tbs

1 cup = 8 fluid ounces (fl oz)

1 tablespoon = 1/2 fluid ounce

2 cups = 1 pint (pt)

2 pints = 1 quart (qt)

4 quarts = 1 gallon (gal)

1 pound = 16 ounces (oz)

water weighs 8.3 pounds per gallon
